lM PROVEMENT IN CORN-PLOW.

Specification forming part of Letters Patent No. 69,109, dated September 24, 1867.

structing a corn-plow, which is simple in its,

construction, and light, and which can be handled easier and with less fatigue than the cornplows now in use.

My invention further consists in hitching the team to the ends of the plow-beams instead of the frame, as is done in other plows, thus producing a more steady draft without vibration of the frame. I

My invention further consists in so hanging the plow-beams in a long slotted piece of timber, pivoted at each end, that the plows will be firm and cannot twist.

My invention further consists in having the shovels elongated at their upper ends, so that the braces also pass through the shovels, thus giving them more firmness, while at the same time the shovels will scour well.

To enable others skilled in the arts to make and use my invention, I will proceed to describe its construction and operation.

Figure l in the drawing is a side view. Fig. 2 is a plan view. Fig. 3, is a section through a b, Fig. 2.

I construct my frame A with timbers B B B, the lower part of which frame A has attached to it two axle-trees, G 0, having between them a space sufficient to let the corn-stalks pass through. The ground wheels D D are attached to these axle-trees, their office being to carry the weight of the frame A and to regulate the pitch of the plows.

The plow-beams E E are hinged to the slotted timbers F F, in which they can move up and down. The slotted timbers F F have trunnions G G at their upper and lower ends, by means of which the plow-beams E E are guided firmly in their sidewise motion. Two iron straps or loops, H H, are passed over the forward ends of the plow-beams E E, and to these the horses are hitched.

There is in the timbers F F a series of holes, I I I I, through either of which the plowbeams E E can be pinned higher or lower, according to thepitch desired.

The plow-beams E E have attached to them four standards, J J J J, to the lower ends of which are fastened the shovels K K K K. Said shovels are provided with projecting tails running upward along the standards J J J J, so that thebraces L L L L can pass through and fasten the shovels at the same time that they firmly brace the standards J J J J.

The handles M M are attached to the plowbeams E E in the usual manner.

Two hangers, N N, fastened to the frame A, have hooks at their rear ends, which can be hooked into the rings 0 O and P P, and thus hold said plow-beams E E suspended when not in use.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The slotted timbers F F, with their holes I I I I and their trnnnions G G, substantially as and for the purpose described in the foregoing specification.

2. The iron straps or loops H- H at the ends of the plow-beams E'E, in combination with the frame A, substantially as and for the purpose described.

3. The shovels K K K K, with their upwardly-projecting tail ends, substantially as and for the purpose described in the foregoing specification.
